If a lightweight implementation, can be as simple as follows:

 
Public static void main (String [] args) {
System. The out. Println (" leave, execute the following code "); 
ScheduledExecutorService durationTimer=Executors. NewSingleThreadScheduledExecutor (); 
DurationTimer. The schedule (new Runnable () {
@ Override 
Public void the run () {
System. The out. Println (" after 3600 seconds, can trigger here, check people ever come back "); 
} 
}, 3600, TimeUnit. SECONDS); 
}
